Ok, I’m not proud, but I can confirm that you can receive 2 bottles of wine at once in coach.
I experienced this last March. In NYC with my four kids to see Hamilton. Staying with our gracious friend in his 2-bedroom apartment. Massive winter storm hits (24+ inches). We are stuck in the city for two extra days, and two extra nights.
We finally get to Newark for our flight. I order a glass of wine as we wait at the gate. Kids have chicken tenders or something like that. Newark has this thing where you can sit at the gate, and order from a touch screen without having to leave your seat! Well, due to weather, we end up spending 5 hours at the gate, my one glass becomes three. When we get on the plane, I order two more glasses of ? Don’t judge! Four kids, small apartment.
In my defense, my husband was along and handled the kids. We finally made it home. All good.
